Vehicle1977 MG Midget
'Third life' of this car, was
restored at some point in the
past. I bought it with no
engine.
MotorNetgain Warp 8 Series Wound DC
(This is the *new* motor)
Whoops! Cooked my Agni 95 until it was
'well done'. The 9HP continuous rating
was
not enough for a hot day, 35mph long drag
uphill.
DrivetrainOriginal 4 speed gearbox.
Drove initially with direct
coupled to driveshaft, but
ended up putting transmission
back in.
ControllerKelly KDZ72553GDV
550A controller with regen. This is a
sepex
controller that works fine with my series
motor.
Still need to set the programming and try
some
regenerative braking.
Batteries9x Nissan Leaf + 2x Chevy Volt 72V, 4.00 Volt, Lithium-Ion
Three banks of 72V Li-ion in parallel.
Two
Chevy Volt and one Nissan Leaf.
System Voltage72 Volts
ChargerJingcheng Jinan E-Shine Electronics Co 60V15A
Jinan E-Shine Electronics Co
Heaternone (yet)
DC/DC ConverterIntelli Power 'Intelligent' DC-DC
Generic ebay DC/DC 72V to 12V. First
tried 15A,
not enough for everything at once (with
lights
on and brake pressed, sounding horn kills
the
12v!). Moved up to 25A, and possibly will
split
car wiring to use both in parallel.
Instrumentation120V 500A unit has been working well:
Ebay: "DC 120V 500A Volt Amp Combo Meter
Battery Charge Discharge Indicator Camper
CAR"

Desire is to enable classic gauges (fuel
from
battery state of charge, etc..)
Top Speed55 MPH (88 KPH)
55 mph, new motor yeah! This
car is flying at 55mph..!
At 45mph, pulling 275 amps. Got better
with the upgraded Li-ion batteries.
AccelerationGreat acceleration with the Warp 8. Don't
have To downshift from 4th gear going
uphill With 2 people.
Range30 Miles (48 Kilometers)
(Est) Getting better with the added Leaf
batteries. Range is the EV equivalent of
muscle
car horsepower.. you can never have
enough!
Watt Hours/Mile230 Wh/Mile
Or stated the other way, 3.25
mi/kWH which seems to be in the
range of typical EV's.
EV Miles
Start:53,123 Miles (85,474 Kilometers)
Current:54,901 Miles (88,335 Kilometers)
Total:1,778 Miles (2,860 Kilometers)

Curb Weight1,550 Pounds (704 Kilograms)

Tires13 inch standard. Looking for low rolling
resistance, but don't seem to be made in
this size.
Conversion Time5 years
Conversion Cost$800 donor car + $500 batteries + $350
controller + $200 charger + $300 misc +
$1100 (Two 72V Volt packs) + $1000 motor=
$4250.
Additional FeaturesPlanning to upgrade headlights and tail/flashers to LED's to
